If there's an intruder in my house or anyone threatening my life pretty much anywhere I'd like to be able to squeeze the trigger and have the highest chance of them dying please and thank you.
Let's be real, an average citizen is not going to need an assault weapon to protect yourself or your family (in fact, with the minimal amount of gun training most have, most likely the casualties will be members of your family, along with the intruder).
Headline: the best way to prevent break-ins are preventative measures, not storing a huge loaded gun in your house. Locking your doors and windows, leaving lights on, and the sort do a much better job preventing break-ins than your assault weapon ever will (unless you have a sign outside that says "I have an assault weapon, and I WILL use it").
It seems you're grasping at straws to explain why an average citizen needs an assault weapon. There are always exceptions to the norm, and exceptions can be made, but the average citizen will almost never need an assault weapon to protect themselves and their home unless they decide to move to Somalia.
I find it hilarious you try to ignore why America has such an alarmingly high number of killings with a firearm and try to explain why the graph itself is "biased" by comparing America with esteemed nations such as Mexico (whose drug cartels run many cities and whose police force is corrupted to the core, and where executions happen daily), Somalia (who doesn't even have a functioning government and is run by factions and militias). In the end, you're unable to explain the high number of deaths by firearms in America; it may not be related to video games, but the high distribution of firearms amongst America's population definitely has something to do with it and the low amount of control. Correlation doesn't imply causation but a reasonable person would find this link probable and reasonable.
Mattj, I'm sorry but you can only belong to the 'MURRICA group if you stop comparing your beloved nation to third world nations and other nations ravaged by drugs and the gun-related violence that comes along with it.
